After following the comic book pretty closely for the last five episodes with only slight deviations, #TheWalkingDead Episode 6, "Swear" went way rogue as we finally caught up with Tara and Heath on the world's longest supply run.

After much speculation that Episode 6 would be a Tara and Heath special, it actually turned out to be extremely Tara-centric, and to be honest I found it one of the most entertaining episodes of the season to date. Tara ended up stumbling across the well hidden Oceanside community, made up solely of a group of badass women and girls, and then truly proved how much of a survivor she'd become when she managed to outwit, outplay and outlast people and walkers all the way back to the gate of Alexandria.

With only two episodes to go until the first half of The Walking Dead Season 7 is over, it looks like we can expect some fairly explosive action in weeks to come, but before we bother thinking about all that take a look at the five thing you might have missed in The Walking Dead Episode 6, "Swear."

1. We were introduced to the Oceanside community!

After over six seasons of The Walking Dead, we knew there were a lot of kickass women, but still it was amazing to see a community entirely made up of them at the Oceanside community. And, while Oceanside is totally different to communities we've seen on the show in the past, it's actually based on a known community from the comic series.

Interestingly, Oceanside was only recently mentioned in the comic series in Issue 139 (the show is currently covering events from around Issue 103 to Issue 111), though with the introduction of so many new communities already in Season 7, it seems like the writers have decided to throw Oceanside in the mix as well.

Unlike the TV show, in the comics the Oceanside base hasn't actually been shown, though we do know that the members — which include men — frequently go out on fishing expeditions. Not only does the community feed themselves with their catches, but it also feeds places such as Alexandria and the Hilltop, establishing a sort of new world trade route.

Given that Oceanside's introduction was accelerated for the TV series it indicates that its residents will probably have a bigger role than they do in the comics, which is exciting because it means we'll get a bunch of original content. Perhaps we'll even see Cyndie (Sydney Park) — who is obviously at odds with her grandma — appear again at Alexandria or somewhere else familiar.

2. The music was extremely appropriate

At the very end of the episode as Tara makes her way home solo, scavenging for supplies in an abandoned boat and sleeping in an abandoned gift shop, the song "Everything's Fucked" by Dirty Three plays in the background.

The song draws to a close as she walks through the gates of Alexandria, and then truly learns how fucked everything is when she's told about Denise, Abraham and Glenn's deaths, and about Negan's essentially take down of the community.

3. Tara's fist bumps made a reappearance

Any Tara fan will know that she's one character who loves a fist bump, and over the years it's been firmly established as her little gesture of trust, friendship and appreciation.

Back in Season 4 she bumped fists with the Governor (a.k.a Philip) after her saved her from her reanimated father, then in Season 5 she fist bumped Rick Grimes after he forgave her for her involvement in the Governor's attack on the prison.

The fist bump made another appearance in Season 5, Episode 5 when she began making friends with Eugene Porter (after he was creepily watching Rosita and Abraham have sex...).

It was a cute little nod to include tara's prefered hand gesture in Episode 6 (though a gesture of another kind also popped up moments later), though Natania definitely needs to work on reciprocal bumps.

4. Tara's mystery tattoos

So this one is kind of a mystery, but near the start of the episode, as Tara pretended to be unconscious on the beach while Cyndie left supplies, it was revealed that Tara had a tattoo on her wrist.

The tattoo is made up of a series of roman numerals: XXVI, XIII, XXII and IX, which translates to 26, 13, 22 and 9. There was also at least a fifth line of the tattoo which we couldn't see due to her shirt cuff.

So what does the tattoo mean? Well it could potentially be a tally of how many walkers per outing she's killed, though that seems a little strange considering it would be easy to forget a kill or two when you're caught up in the moment. Another possibility is that it's code for the letters Z, M, V and I, but then that raises the question of what those letters stand for or spell. A commenter on one forum even suggested that it could be pointing to various passages in Proverbs, something which is totally possible considering the show's love of bible references. Here's the verses the numbers correspond to (from the New International Version of the bible):

Proverbs 26:13 NIV: A sluggard says, "There’s a lion in the road, a fierce lion roaming the streets!"

Proverbs 22:9 NIV: The generous will themselves be blessed, for they share their food with the poor.

While this is just a theory, you have to admit, the "lion in the road" could definitely be a Negan reference, while the second verse may have something to do with a future arrangement between Oceanside sharing their fish supplied with the other communities. What do you think - got some theories of your own about what the tattoos mean?

5. What does 'PPP' mean?

After risking life and limb escaping Oceanside residents and then some sandy walkers, Tara finally made it relative safety on the other side of the bridge only to find Heath missing, some muddy tire tracks and a keycard with the letters 'PPP' written on it. While Tara doesn't seem to recognize the card or the letters as anything significant, saying "maybe that was you. I hope that was you," it does seem like the card was likely left by Heath, or someone harmless.

So what could it mean? Some have theorized the Saviors collected Heath, and that 'P' could be his prison ID (as you'll remember it seems like all the prisoners have uniforms spray painted with giant letters), though for some reason the card denoting this was dropped. Others think that it may be Heath's way of leading Tara to him, reasoning that in computer networking PPP means Point-to-Point Protocol, a data link used to establish a direct connection between two nodes. It could also be a fun nod to the movie Peach Plum Pear that Tara a.k.a Alanna Masterson starred in back in 2011. What are your leading theories on PPP?

The Walking Dead returns to AMC with Episode 7, "Sing Me A Song" on December 4 at 9pm ET.
